I have selected map tiles from NW Trails and NW Topo to upload to my 60csx. I had older versions of the maps on the 60 and all was fine but as I have installed a new, formatted 2gb card, I downloaded the latest versions of Trails and Topo to upload. Tried twice, but after the mapset is built I get an error:

"The mapset is approximately 419.8MB, but only 1883.7MB is available in the destination. Please select fewer maps and try again."

Does not make sense to me as the error message indicates that the available space is plenty?

Anyone know where I am going wrong?

Thanks!

I can transfer either one by itself just fine, so I have Trails on the 60csx now. But I remember that when I originally uploaded the maps I did combine tiles from both Topo and trails and uploaded them at the same time.
